[ubuntu] Ads in "Search your computer"

Hi Ubuntu-ers,

I'm sort of new to ubuntu, but very new to the forums. In the latest install of ubuntu I noticed that if you hit the windows key on the keyboard, or click the icon in the coer of the taskbar you can search your computer very much like the spotlight search in mac. This is an awesome feature.

However, in searching for my computer, the results are showing advertisements from the web. Most recently I searched "firefox" because that's how I open my browser and below the files on my computer were a list of links to items with price tags.

This pisses me off incredibly and I want to make it go away before I throw my computer out the window in a fit of rage.

...so, does anyone know how I can make the "search your computer" command search only my computer?

Thanks
